FRITZ SCHENDEWOLF, OF NEW YORK, N. Y., ASSIGNOR TO B. E. DIETZ COMPANY, OF NEW YORK, N. Y.

LAMP OR LANTERN.

Specification of Letters Patent.

Patented Oct. 9, 1906.

To all whom it may concern:

Be it known that I, FRITZ SCHENDEWOLF, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Lamps and Lanterns, of which the following is a specification.

This invention relates to that class of lamps or lanterns in which the body is provided at its lower end with a supporting or attaching ring for the reception of the detachable oil pot or base. A lamp of this kind is described and shown in Letters Patent No. 744,952, dated November 24, 1903.

The object of this invention is to secure the supporting-ring to the lamp-body in a simple, neat, strong, and durable manner and to cover the opening for the wick-raiser shaft by a movable slide or cover which is simple in construction, which stiifens the slotted portion of the body, which can be quickly applied, and which presents no objectionable projecting parts on the inner side of the body.

In the accompanying drawings, Figure l is a side elevation of a vehicle-lamp provided with my improvements. Fig. 2 is a perspective view of the lower portion of the lamp. Fig. 3 is a side elevation of the lower portion of the lamp-body. Fig. 4 is a sectional elevation of the lower portion of the lamp-body. Fig. 5 is a vertical section in line 5 5, Fig. 4, on an enlarged scale. Fig. 6 is a perspective view of the movable cover for the wickraiser slot. 4

Like letters of reference refer to like parts in the several figures.

A represents the body-hoop or lower portion of the body or frame of a lamp or lantern, which may be a vehicle-lamp, as shown.

B represents the hollow supporting or attaching ring, secured to the lower edge of the body-hoop, for the reception of the oil-pot C, which is inserted into this ring from below and secured thereto by detachable fastening devices provided on the oil-pot and on this ring. The fastening devices for this purpose,

which are described and shown in the above mentioned Letters Patent, comprise a springcatch D, which is mounted on the side of the oil-pot and engages in an opening (I in the supporting-ring B upon turning the oil-pot in the ring; but other suitable fastening devices may be employed.

The body-hoop A is provided at its lower edge with an inwardly-projecting flange or lip e, to which the supporting-ring B is secured by a lock-seam which is constructed as follows: The top Wall f of the supportingring is provided with a raised annular shoulder g, which surrounds the lower edge of the body-hoop and which consists of an outer portion extending upwardly from the top wall and an inner portion extending downwar ly from the upper end of the outer portion. The top wall extends inwardly from the lower end of the inner portion of this shoulder and is bent to form an outwardly opening hook h, which embraces the flange e and is bent aroundthe same and closed by suitable pressing dies or tools. This seamed joint can be closed by a single stroke of the press and secures the parts together in a very neat and secure manner and at very little expense and avoids the use of solder for this purpose. The external shoulder 9 holds the parts properly in position before the seam is closed and also renders the completed connection very strong and durable.

I represents the usual angular slot, which is formed in the body-hoop for accommodating the wick-raiser shaft 7c and which consists of an upright portion '6, which opens downwardly through the flange e, and an upper horizontal portion i.

L represents the usual T-shaped. opening, which is formed in the top wall f of the supporting-ring for the passage of the wickraiser shaft and the wick-raiser button m and which consists of a segmental outer portion 1 and an inner portion Z which opens upwardly through the shoulder g and hook h-of the supporting-ring and connects with the upright,

portion 1', of the slot I.

N represents the sliding cover, which is arranged against the inner side of the bodyhoop for covering the slot I. This cover is curved so as to lie snugly against the inner side of the body-hoop and is provided in its lower portion with a downwardly-opening notch n, by which it straddles the wickraiser shaft, so that the cover moves with the latter when the oil-pot is turned in the supporting-ring. The cover N is held movably on the body-hoop by a headed stud O, the neck of which is of the proper size to move in the horizontal portion i of the slot I, while the head of the stud extends above and below the slot, so that the cover bears against the inner side and the head of the stud against the outer side of the body-hoop. The cover can be moved oircumferentially in the bodyhoop with the wick-raiser shaft in applyin or removing the oil-pot, and as the cover an stud bear against opposite sides of the slotted portion of the body-hoop they serve to hold these portions in position and support particularly the tongue or the portion of metal 29, which lies below the horizontal portion 11' of the slot I in the body-hoop and which is otherwise unsupported at its free end, adjacent to the junction of the upright and horizontal portions of the slot. The head of the stud is of such size that it can be passed through that portion of the slot I which forms the junction of the upright and horizontal portions thereof, so that the cover can be inserted into the body-hoop after the supporting-ring B has been secured thereto, as represented in Fig. 3. The cover or slide N is held in the body-hoop by the stud without the employment of inwardly projecting parts, thus leaving the interior of the lamp free from projections, which are objectionable because they catch dirt.

I claim as my invention 1. The combination of a lamp or lantern body having an angular slot for the wickraiser shaft and a sliding cover provided with a notch for the wick-raiser shaft and arranged against the inner side of said body and connected therewith by a headed stud which is arranged in said slot and bears with its head against the outer side of said body, substantially as set forth.

2. The combination of a lamp or lantern body having an angular slot for the wickraiser shaft and a sliding cover provided with a notch for the wick-raiser shaft and arranged against the inner side of said body and connected therewith by a headed stud which is rigidly secured to said cover and adapted to be passed with its head through the angular portion of the slot in applying the cover to the body or removing it therefrom, substantially as set forth.

Witness my hand this 31st day of May, 1905.

FRITZ SCHENDEWOLF.
